Ancient/Iron Age Tribal names....Latin or Local.

[Urselius]

Eburacum, became Eoforwicescaestre in Ango-Saxon, which retains the Celtic/Latin structure Ebor-vicus-castrum almost unchanged, except that 'eofor' meant wild boar in Old English, so that the English would have considered it to mean Boar-town-fort. The Vikings then changed it to Jorvik which then became York. Eburacum and York do not look connected as names but they are; many other apparently entirely English names probably conceal Celtic origins in a similar way.
